<<See All OBD Codes

Is your vehicle’s instrument panel flashing Check Engine Light? Is your vehicle giving you serious performance issues or are you facing problems while starting? All these issues are related to obd error code P048E. OBD error code P048E might also result in other exhaust back pressure related codes. For a problem related to so many issues, its needed that you have a deeper knowledge.

Wondering what this alien word obd P048E actually means? Well, in a layman language we can say that it is code indicating a problem with exhaust pressure control valve position sensor circuit being high. To put it more simply it indicates an open circuit. To know more about this error code and few of its related causes, have a look at our subsequent sections.

What causes this problem with the Exhaust Pressure Control Valve Position Sensor/Switch Circuit High?

• Dysfunctional EPC (exhaust pressure control valve)
• Faulty EPC wiring and circuits
• Malfunctioning powertrain control module
• Open or shorted exhaust pressure control valve harnesses
• Bad electrical connections

1. Exhaust Pressure Control Valve - When OBD code P048E flashes on your instrument panel, chances are that there is a problem with your EPC valve circuit. Replace the damaged ones with brand new ones only at Parts Avatar Canada.
2. Exhaust Parts - When it comes to car repairs, there are chances that not only one but several parts are damaged and demand replacement. So is the case with fixing obd code P048E, you might need new exhaust parts to get rid of the issue.
3. PCM - if you need engine control module or powertrain control module to correct your obd error code P048E then you can simply browse through our PartsAvatar website and get your hands on the best selection of parts available.
4. Manifold Absolute Pressure Sensor - if you are facing OBD error code P04E then it might demand a new MAP sensor if found faulty. If you wish to get it done at the earliest then you can simply browse through our website to find one for your make and model. We have in stock for you high end MAP sensors from top brands.
5. Intake Air Temperature Sensor - Considering that pcm takes signal from MAP sensor, IAT sensor and EPC sensor together, either of them if damaged can lead to problems. So replace the faulty IAT sensors today.
6. Diagnostic Tools - You can choose from a selection of diagnostic tools on our website and make it easy for yourself when diagnosing problems such as obd error code P048E and creating accurate solutions for your car.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P048E here:

Common Symptoms

• Fall in overall engine efficiency
• Flashing of Check engine light (CEL)
• Starting problems such as hard starting
• Rise in vehicle emissions

In order to correct this OBD Code P048E you will need to undergo the following steps and might need the following parts.

• Exhaust pressure control valve position sensor replacement, if found faulty.
• EPC wirings and connectors if found faulty.
• You might need to replace a faulty pcm too.

Also, make sure that your vehicle’s PCM and all exhaust parts, IAT sensors and MAP sensors are in good working condition to ensure the disappearance of this fault code P048C.

There is no need to get strained if your OBD Code P048E is still flashing up as we are here at your service. Have a look at our superior variety of EPC sensors, MAP sensors, IAT sensors and many more. Now all your problems would vanish within no time.

Now, in order to correct the problem, it is extremely essential to diagnose it efficiently and appropriately. While doing so you might commit few mistakes, to prevent you from doing so we have listed out few steps for you to keep in mind.

Firstly, scan the codes and then freeze the frame data and after that you will have to scan the engine control module for the code and then freeze the frame data. Now, if you come across any coolant temperature or air intake temperature codes, fixing them before attempting to fix P048C is must. Also look for the technical service bulletins to guide you through your diagnosis. Also check the factory diagram to ensure what wiring is supposed to be where in order to diagnose the issues with it. In order to check and test the solenoid, remove the solenoid connectors after the vehicle is cooled down. After that use a digital multimeter, while keeping the ignition on to check the solenoid power. It usually should be 12 V. In case the readings exceed, then there is an open circuit. Also, check the ground portion of the circuit and the power side of the circuit.
